Exercising device



INVENTOR HIS ATTORNEYS My ta June 29, 1937. A. KRAUS EXERCISING DEVICEFiled July 12, 1935 Animal F1229 Patented lune 29, 1937 TA'E'ES 2Glaims.

My invention relates to exercising devices, and has among its objectsand advantages the provision of an improved punching bag.

An object of my invention is to provide a punching bag characterized bya quick recovery after being struck and in which the bag is shaped tosimulate the head and body of a boxer. The bag also embodiesa noveljointed structure operating to minimize the force of the recoil and inwhich the head part of the bag is jointedly connected with the body.

In the accompanying drawing: Fig. 1 is a plan view of the device; Fig. 2is a sectional View along the line 22 of Fig. 1; and

Fig. 3 is a sectional view along the line 33 of Fig. 2.

In the embodiment selected to illustrate my invention, the figure Ill,including a head part I2 and a body part it, is mounted upon a standardI 6 mounted upon a spring structure I8 fixedly connected with a plate 20anchored to the floor 22. The spring l8 yields when the bag is struck topermit oscillation of the bag, and operates to impart a quick returnmovement to the bag.

The body I4 comprises a covering 24 filled with padding 26 such ascurled hair or other suitable fibrous material. The covering 24 extendsaround the head l2 and has its bottom end sewed at 28 to a bottom part30 having an opening for the reception of the shaft 32. The

latter is provided with a flange 34 against which the part 30 bears. Iplace a plate 36 against the outer face of the part 36 and securelyfasten the latter between the flanges 34 and 35 by screws 38.

To the upper end of the shaft 32 I connect a joint til which in turn isconnected with a shaft $2 extending vertically through the head 52. Thejoint do is of a bendable nature to permit bending of the punching bagat a point slightly below the neck 45. When the device is struck abovethe joint M3, the head portion is thrown back. In cases where the bag isstruck below or in the locality of the joint $0, the force imparts abending action to the device. In addition to providing a jointed figuresimulating the body of a boxer, the joint performs an important functionin breaking the force of the recoiling bag. When the back is struckduring a rapid recovery movement, the bending action bends to break theforce of the impact which might otherwise injure the user.

Specifically the joint 40 comprises a flanged member 46 having threadedrelation with the threaded end 48 of the shaft 32. Similarly, thethreaded end 5i! of the shaft 62 is provided with a flanged member 52.Upon the neck parts 54 of the two members 35 and 52, I mount a coilspring 56. This spring is close Wound, preferably with initial tension,and has threaded relation with the necks 56 of the members 46 and 52.Upon the spring I mount a rubber casing 58 to prevent the material ofthe bag from working between the convolutions of the spring.

Within the cover 28 encircling the head l2, I mount an inner covering58. The lower end of this covering is wrapped firmly about the shaft 42as at 62 adjacent the flange G l upon the shaft. The upper end of theshaft 42 is provided with a flange 66 against which the covering lies. Iposition a disc 58 in vertical alignment with the flange 66 and pinchthe coverings 2L and 50 securely therebetween by means of screws Iii.

One end of the spring 12 of the structure l8 has threaded relation witha post M having a neck 16 at its lower end. This neck passes through anopening in the plate 28 and is firmly secured thereby by riveting theend of the neck. The upper end of the spring 12 has threaded relationwith a sleeve I8 slidably mounted upon the shaft 32.

I mount a cone shaped tube 86 upon a flange 84 through the medium ofscrews 88. This flange has its upper end terminating in close relationwith the bottom of the body E5. The tube 86 enhances the ornamentalappearance of the bag.

Within the spring '52 I mount a second spring 90 of the same type as thespring 55. One end of the spring 90 has threaded relation with a post 92positioned within the bore 94 in the post M. The post 92 passes throughan opening 96 in the post 14 and is made secure by riveting its end at98.

The lower end of the shaft 32 has a threaded reach I on upon which Imount a flanged member I02 for connection with the spring 3 9. Themember I02 has threaded relation with the spring 98. Normally the springstructure i8 supports the bag in the vertical position of Fig. 1. Thespring structure imparts a rapid rebound of the figure so as to positionthe figure in a vertical position by the time that the user is ready foranother blow.

In providing a padded figure, I eliminate the necessity for inflatingequipment. The bag structure is of durable construction in that Ieliminate deflation of the bag in the event of damage to the covering.In addition, the bag is padded to a degree of firmness simulating thebody of an adversary.

Without further elaboration, the foregoing will so fully explain myinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.

I claim:

1. An exercising device comprising a striking bag including a lower partand an upper part, shafts extending through portions of said parts andbeing arranged in spaced, axial alignment, said shafts being anchored tosaid parts, said parts being padded with a resilient material, aresilient universal connection between said shaft parts and housedWithin the striking bag, said resilient universal connection operatingto urge the shaft parts to their axial aligned positions, a base, andresilient means connecting the base with one of said shafts for urgingthe bag toward a vertical position and eifecting a quick recovery of thebag.

2. Anexercising device comprising a striking bag including a lower partand an upper part, said bag being padded With a resilient material,shafts positioned within both parts and normally arranged in axialalignment, a convoluted spring having its ends connected with saidshafts, said spring urging the shafts to their normal position, a tubeof resilient material enclosing the convoluted spring, to preventpadding from working between the convolutions of the spring, one of saidshafts extending to a position exteriorly of the striking bag, a base,and a resilient connection between the base and the shaft part extendingexteriorly of the bag.
